text: Chlorinated paraffins (CPs) are complex mixtures of polychlorinated n-alkanes (paraffin wax). The chlorination degree of CPs can vary between 30 and 70 wt%. CPs are subdivided according to their carbon chain length into short-chain CPs (SCCPs, C), medium-chain CPs (MCCPs, C) and long-chain CPs (LCCPs, C). Depending on chain length and chlorine content, CPs are colorless or yellowish liquids or solids.
